These three cables, what would you choose?


I've recently graduated from Law school and as a present to my self I have started to rebuild the hi-fi, similar to the one I sold to go to law school.  So what I've wound up with is Mirage M1s, proceed amp three, and proceed avp pre/pro. I'll probably get a musical Fidelity USB v90 dac as my source. 
So the question here is which speaker cable to gravitate towards.
Mid-level older audioquest, like crystal plus. 
Or...
Tara labs rsc prime 500
Or...
Dh labs t14
My last system I had was a classe CA200 with mirage M1's and I had Tara labs temporal continuum, and I really enjoyed it. I'm wondering if the RSC prime 500 would be similar to the temporal continuum, or if there not even close.  Please while your sitting around this holiday weekend, tell me your thoughts whether you've had the cables and your experience with them

I used to be a Mirage dealer. Do you have the first gen M1's with the soft tweeters or the second gen with the aluminum tweeters? That's important because there's a big difference between the two.

Assuming this system is going to be used for stereo 2 channel listing, (no surround) you may want to change your preamp first. It will make a far bigger difference than cables.
I appreciate the response, the mirages are not the si, but are able to be biwired. They have the little bar over the tweeter. As far as the pre-amp, I rather like the proceeds pre/pro, I'll be moving towards home theater eventually. But for now it's just a two channel.
The dh labs are nice but about a 100 bucks more than I planned to spend, that's why I mentioned the 14's
